The syntheses, properties, and biological applications of the Peroxysensor family, a new class of fluorescent probes for hydrogen peroxide, are presented. These reagents utilize a boronate deprotection mechanism to provide high selectivity and optical dynamic range for detecting H2O2 in aqueous solution over similar reactive oxygen species (ROS) including superoxide, nitric oxide, tert-butyl hy...

Anaplasma marginale prevalence was determined in 223 sera samples in 2-year old or older cattle, from the Center-Southern Region of the Paraná State, including Ponta Grossa, Guarapuava and Laranjeiras do Sul municipalities. A survey of antibodies IgG class against Anaplasma marginale was performed through a competitive immune absorbent assay (cELISA-PR1). From the 223 sera examined, 130 (58.74%...

We use neutron scattering to investigate the doping evolution of the magnetic correlations in the single-layer manganite Pr1-xCa1+xMnO4, away from the x=0.5 composition where the CE-type commensurate antiferromagnetic (AF) structure is stable. We find that short-range incommensurate spin correlations develop as the system is electron doped (x<0.5), which coexist with the CE-type AF order. This ...

homologs are NAD + -dependent deacetylase enzymes that play important roles in a variety of physiological processes. However, the functions of the Sir2 family in plants are poorly understood. Here, we report that Arabidopsis AtSRT2, a homolog of yeast Sir2, negatively regulates plant basal defense against the pathogen Pseudomonas syringae pv. tomato DC3000 ( Pst DC3000). In response to Pst DC30...

Wild rice, Oryza grandiglumis shows hyper-resistance response to pathogen infection. In order to identify genes necessary for defense response in plants, we have carried out a subtractive hybridization coupled with a cDNA macroarray. An acidic PATHOGENESIS-RELATED1 (PR1) gene of the wild rice is highly identical to the acidic PR1 genes of different plant species. The OgPR1a cDNA has an apparent...

The silent information regulator protein (Sir2) and its homologs are NAD(+)-dependent deacetylase enzymes that play important roles in a variety of physiological processes. However, the functions of the Sir2 family in plants are poorly understood. Here, we report that Arabidopsis AtSRT2, a homolog of yeast Sir2, negatively regulates plant basal defense against the pathogen Pseudomonas syringae ...

An ultra-low-power, 4-channel 2 – 1 PRBS generator with 60 mW per channel was designed, fabricated and measured to work up to 23 Gb/s. The circuit is based on a 2.5-mW BiCMOS CML latch topology, which, to the best of our knowledge, represents the lowest power for a latch operating above 10-Gb/s. The chip also includes an integrated PRBS checker and error counter.

Previously, we have demonstrated that GBX genes, a homeobox-containing human family of DNA-binding transcription factors consisting of GBX1 and GBX2, are overexpressed in a panel of human prostatic cancer cell lines (ie., TSU-pr1, PC3, DU145, and LNCaP) compared to normal prostate. In the present studies, specific primer sets were designed for reverse transcription-PCR detection of the expressi...
